switching from nuva ring to iud-what to expect?

Isabelle • 😚😚😚
I've had the nuva ring for over three years and have been really satisfied with it, but with the trump presidency now I'm worried that the price will go up from it being free to it being really expensive. I'm seriously considering an iud but I have some questions: what's the best brand? what should I expect initially? will it help with acne? what's a copper iud? any tips in general? Thanks for any help!
